Html2Xhtml is a .NET 4.0 library for converting HTML to XHTML licensed under GPLv2 or above.
I tested Html2Xhtml in the local reconstruction of a large online database of the European Union. Tidy/Tidy.NET would not even produce valid output most of the time, Chilkat's HTML-to-XML was a bit slow and produced strange results (misplaced, missing, unexplainable elements). In attempt to find a free, fast and reliable conversion tool I created this library. It converts 2 - 4x faster than all other libraries I tested.
Html2Xhtml, combined with the power of LINQ to XML, is an excellent tool for all large-scale data extraction and web crawling scenarios.
